The Tamiya TT01 Graphite Thick 2.5mm Upper Bumper GPM GTT220 is built to give the TT01 a firmer top plate that resists bending under load. Made from quality graphite, this hop-up increases the chassis rigidity that helps maintain predictable handling on mixed surfaces. At 2.5mm it strikes a balance between added strength and minimal mass, making it a practical upgrade for club racing and spirited bashing.
